Terrorism was a top story in other parts of the world. In March, suspected Islamic militants exploded bombs on crowded passenger trains in Madrid, Spain. About 200 people were killed. Days later, Spanish voters defeated the country’s conservative government, which had supported the American-led war in Iraq. In September, armed Chechen militants seized more than 1000 children, parents and teachers in a school in Beslan, Russia. The seizers ended in gunfire and explosions after days of negotiations. More than 300 people were killed, most of them children.
